```							Dear Student If x and y are integers then y-3 will.also be a integerHence factor of 5 are = 1 *5 or 5 *1NowIf x = 1, y-3 = 5X = 1, y = 8Hence x +y = 9 But if x = 5, y-3 = 1X = 5, y = 4Now x + y = 9 Hence ij every case answer is option B RegardsArun (askIITians forum expert)

```							product of two integers = 5  the only way this can happen is if the integers are either 5&1 or -5&-1let x=1 and y-3=5   add these equations x+y=9let x=5 and y-3=1 then x+y=9 again now let x=-1 and y-3=-5 then x+y=-3similarly x=-5 and y-3=-1 will give x+y=-3So answer is B,C
